The present invention aims vto eliminate the aforesaid disadvantages and has for ione object the provision of a valve of the kind described, the operating parts for which are enclosed :andisealed against the admission of the tank lading.- l. 3 J- A further object ofthe present iiUVQIiblOh is the' provision of a valve formed of few parts which, if occasion arises; inay be easily and quickly replaced. a a. v q Another object of thefipresent invention is theprotision rof a bell -shaped iralireytheoperating [parts for which are -cont aine"d withinsai'd ,valve and are so arranged {that they are sealed against the admission "of tank ladin'gr t Other objects and advantages oit this invention will be apparent from the fouowmrg description, taken in conjunction with the accompanying drawingsyin which:

Fig. is a vertical sectional view of a portion er the valve screw and guide; showing a modified form of naive screw retainer. Referring now. niore. parti'oiilarly to the v drawings, in which silrni-lzn" "characters of reference 'dsignate siinilar parts in the several views,- in 1, A indicates a portion of the bottom oif'a car tank, the same havih'g an openin'giadjacent which the outlet B is secured. 'as by rivets 2'. The valve asseinblage of the present invention is shown "enemuy at G arfdfcoih prises the valve eleihent D, the Valve c'arriei" or screw block E and the silpporting giiide-e'lenrentF to which said screw jb'l'ook E is secured; i l

The outlet B is "preferably tuhnlar as shown, and the upperrendtherofi's fo i-rhed with a lateral attaching flange 3 and with "a beveled surface A redefining a seat for the riali'ze ele'me'nt D. The outlet B is also inte" riorly threaded adjacent the wvalve *seat 4:

whereby to "secure the screw b'ldck snpportelement and Yalve gfiide F', the latter comprising a cylindrical. :strtictnre the uppei end or which is provided with a head 6 and the w'al1'8 ofisaid striictnre having discharge ports 10 formed therein to perinit the discharge of tank lading therethrough into the outlet 5B; i i

.As shown clearlyin 1', the lower end er guide F is flanged :as at 12 and said flange is "exteriorl y threaded .toengage the interior" 2 threads of the outlet Bwherehy' to secure the gnide'in thecontlet. To prevent a'cgiidental rotation .of the guide F, a set screw 14 is flange 12 =aridextnds into the outlet. 7

The side edges of 'the wall 8 adjacent the {ports 1'( therein are o itwardly flanged has shown at 16 to proi ide guide ribs-for vaive D; as will he hereinafter pointed ont.

In carrylng out the present i hventijqn a valve carrier or screw block iE TS provided 90 employed which is arranged through the which is supported :bjr a'n'd 'secu'iie'd to the gni'de 'F thebloc'k beingsuhstantially :dlimh- 26 which extends through the lug 22 and through av keeper plate or retainer 28.

The keeper plate 28 is preferably of the' form shown clearly in Fig. 4 and is provided with oppositely arranged flanges 30, one of which has a tongue 32 struck therefrom to engage a shoulder 3% formed in the lug 22 as clearly shown in Fig. 2, and one end of the opposite flange is adapted to abut a lug 36 formed on the lower surface of the head 6 also as shown in Fig. 2. As before-mentioned, the block E is dumb-bell in shape, providing the spaced flanges 38 each of which is provided with an annular recess in which is seated a sealing ring 40 formed preferably of cast iron or other suitable material, which engage the inner surface of the valve D as shown in Figs. 1 and 3, whereby the interior of the valve assemblage and hencethe operating parts thereof, are sealed against the admission of tank lading.

The valve D is preferably bell-shaped, comprising the squared portion 42 and the head 44, the lower edge of the squared portion being beveled and machined so as to have a nice fit with the valve seat 4;.

The head 44 is provided with an integral upstanding boss 46 and a depending socket 48 which receives the squared lower end of a valve rod 50; the interior of the socket being, of course, correspondingly squared whereby rotation of the valve rod 50. will rotate the valve element D. The socket is preferably circular in exterior cross section and the outer surface thereof is threaded as at 52 to work in the internal threads of the screw block E. i

The valve rod 50 extends upwardly through a bracket 54 of suitable or desired construction and is provided with a pin 56 to limit the upward movement of the valve; the pin 56 being so positioned on the valve rod relative to the bracket 54 that upon elevation of the valve D, the pin 56 will strike the bracket 54 and limit the upward movement of the valve element D prior to the time when the lower edge of said valve element reaches the lower sealing ring 40, thereby preventing the piston rings being exposed and also preventing the admission of the tank lading to the interior of the valve assemblage above the guide F.

Fig. 5 discloses a modified form of keeper or retaining means for the screw block, and in this figure, it can be seen that the head 6 of the guide is provided with a depending flange 58 adjacent an opening formed in said head through which opening the lug 22 of the screw block E extends. For securing the screw block E to the guide F, a suitable fastener such as a bolt 60 is employed, which passes through the flange 58 and the lug 22, thereby rigidly securing the screw block E and the guide F.

From the above description, it is believed that the operation of the valve of the present invention will be fully apparent, but attention is called to the fact that upon rotation of the valve rod 50, the valve element D will be elevated because of the engagement of the socket 4:8 with the screw block E. A reversal of rotation of the'valve rod 50 will obviously lower the valve to its seated position. With the valve assemblage positioned as shown in Fig. 1, it is apparent that the tank lading is prevented from discharging into the outlet, and it will. be obvious that upon elevation of the valve to the position shown in Fig. 3, the rings 40 effectually seal the interior of the valve against the admission of the tank lad-' ing. In lowering the valve by means of the valve rod 50, it will be apparent that the valve is guided to its seated position by means of the flanges or ribs 16 formed on the guide F adjacent the ports 10 therein.

- The drawings herein disclose the preferred embodiment of the invention, but it is to be understood that these drawings are for illustrative purposes only and that various changes in the form and proportions of the device may be made within the scope of the appended claims without departing from the spirit of the invention.
